K&F Concept Nano-X 2-in-1 filter: Black Mist 1/4 and variable ND8–ND128 72 mm

Nano-X 2-in-1 filter: Black Mist 1/4 and variable ND8–ND128 72 mm. It suits backlit portraits and video on bright days, where the light needs cutting and the picture softening at the same time, without screwing two filters onto the lens.

• Screws onto a lens with a 72 mm thread.
• The surface repels water and grease and resists scratches

Softer highlights, a film look

Black Mist scatters the light around bright areas — street lamps take on a gentle glow, blown highlights soften and skin loses its digital hardness. Contrast in the deep shadows drops a little, so the picture looks more filmic straight out of the camera. Unlike an effect added in post, the diffusion follows the actual light in the scene.

The surface repels water and grease, so drops run off and fingerprints wipe away without smears; the coating also stands up to cleaning in the field. The glass does two things at once: it diffuses highlights like a Black Mist 1/4 and cuts three to seven stops at the same time. A backlit portrait can be filmed wide open even at midday, with no filters stacked.
